Subject: [PATCH net-next v3 0/2] net: update netdev_rx_csum_fault() print dump only once
Date: Mon, 28 Jun 2021 09:50:05 -0400	[thread overview]
Message-ID: <20210628135007.1358909-1-tannerlove.kernel@gmail.com> (raw)

From: Tanner Love <tannerlove@google.com>

First patch implements DO_ONCE_LITE to abstract uses of the ".data.once"
trick. It is defined in its own, new header file  -- rather than
alongside the existing DO_ONCE in include/linux/once.h -- because
include/linux/once.h includes include/linux/jump_label.h, and this
causes the build to break for some architectures if
include/linux/once.h is included in include/linux/printk.h or
include/asm-generic/bug.h.

Second patch uses DO_ONCE_LITE in netdev_rx_csum_fault to print dump
only once.

Tanner Love (2):
  once: implement DO_ONCE_LITE for non-fast-path "do once" functionality
  net: update netdev_rx_csum_fault() print dump only once
